Vueroid D21-4K Ultra HD 4K Front and Full HD Rear 2-Channel Dash Cam with AI ADAS
A 2-channel dash cam from Vueroid, the D21-4K records the front in 4K Ultra HD at 30fps via Sony STARVIS 2 (IMX678) and the rear in Full HD 1080p via Sony STARVIS (IMX307), with dual-band Wi-Fi, built-in GPS, HDR, Ultra Night Vision, Ultra LP Capture for licence plate identification, AI ADAS with six alert types, Cyclops safety camera alerts, FAT32 file system, flexible voice recording modes, three parking surveillance modes, heat monitoring, and battery discharge prevention. All units include front and rear cameras and memory card. Wi-Fi requires optional Wi-Fi dongle.
Product Overview
The Vueroid D21-4K is a 2-channel dash cam delivering 4K Ultra HD front recording from a Sony STARVIS 2 IMX678 sensor at 3840 x 2160 and 30fps, combined with Full HD 1080p rear recording from a Sony STARVIS IMX307 sensor. The front camera provides a diagonal 165-degree field of view and the rear provides 139 degrees diagonal, minimising blind spots from both directions.
HDR technology preserves detail in extreme lighting conditions including high brightness, backlighting, and tunnel transitions. Ultra Night Vision automatically optimises exposure, shutter, gain, gamma, and black level settings for clarity in extremely low-light conditions. Ultra LP Capture identifies vehicle licence plates both when stationary and moving, and in very low-light environments, providing valuable evidence in hit-and-run and night-time incidents.
The AI ADAS system delivers six alert types including Forward Pedestrian Detection (FPD), Rear Pedestrian Detection (RPD), Forward Collision Warning (FCWS), Rear Collision Warning (RCWS), Front Vehicle Start Alarm (FVSA), and Lane Departure Warning (LDWS). Cyclops safety camera alerts warn drivers of upcoming speed and red light cameras.
Flexible voice recording modes cover MIC on/off, Event only, and Event+Motion, addressing privacy concerns while ensuring audio capture in accident events. The FAT32 file system allows video playback, copying, and sharing via any standard viewer without requiring proprietary software. MicroSD support covers 16GB to 256GB. Three parking surveillance modes are available: Time Lapse (1fps), Sleep and Wake Up (impact-triggered wake), and Motion Detection. Heat monitoring automatically enters power-saving mode when high temperatures are detected, transitioning back to parking mode once cooled. Battery discharge prevention cuts power when voltage drops below the preset threshold. All units include front and rear cameras and memory card. Professional installation is recommended, particularly for parking mode activation via hardwire.
Features & Benefits
4K Ultra HD Front Recording - Sony STARVIS 2 IMX678: The front camera captures 3840 x 2160 at 30fps via Sony STARVIS 2 IMX678, delivering cinematic 4K clarity for road signs, licence plates, and incident detail with the highest image quality available in the D21 range.
Full HD 1080p Rear Recording - Sony STARVIS IMX307: The rear camera captures Full HD 1080p via Sony STARVIS IMX307 for comprehensive rear coverage with strong low-light performance.
HDR Technology - Detail in All Lighting Conditions: HDR processing delivers clear and vivid footage in any driving environment, preserving detail in scenes with extremely high brightness, backlighting, and sudden lighting transitions such as tunnel entrances.
Ultra Night Vision - Automatic Low-Light Optimisation: Ultra Night Vision automatically optimises exposure, shutter, gain control, gamma, and black level settings for vivid, clear footage in extremely low-light conditions, going beyond standard night vision for improved visibility in the darkest conditions.
Ultra LP Capture - Licence Plate Identification Moving or Stationary: Ultra LP Capture identifies vehicle licence plates when stationary and in motion, and in very low-light environments, providing accurate licence plate information for hit-and-run evidence and night-time incident documentation.
AI ADAS with Six Alert Types: The deep learning-based AI ADAS delivers six real-time safety alerts covering Forward Pedestrian Detection (FPD), Rear Pedestrian Detection (RPD), Forward Collision Warning (FCWS), Rear Collision Warning (RCWS), Front Vehicle Start Alarm (FVSA), and Lane Departure Warning (LDWS), providing comprehensive hazard awareness across all driving scenarios.
Cyclops Safety Camera Alert: Cyclops alerts warn drivers of upcoming speed cameras, mobile camera zones, and red light cameras to promote safer driving and speed compliance.
Flexible Voice Recording Modes: Three voice recording modes (MIC on/off, Event only, Event+Motion) provide privacy flexibility while ensuring audio capture is activated automatically in the event of an accident.
FAT32 File System - Universal Video Playback: The FAT32 file system allows recorded videos to be played, copied, and shared via any standard video viewer by inserting the memory card into a PC, without requiring proprietary software for basic file access.
Three Parking Surveillance Modes: Time Lapse records at 1fps for extended parking coverage with minimal storage consumption, Sleep and Wake Up enters standby with 2-second impact-triggered wake, and Motion Detection captures activity around the parked vehicle. Requires hardwire installation.
Heat Monitoring and Battery Discharge Prevention: Heat monitoring automatically transitions the unit to power-saving mode during extreme temperatures and returns to parking mode once cooled. Battery discharge prevention cuts power at the preset voltage threshold to protect the vehicle battery.
Built-in GPS and Dual-Band Wi-Fi: Built-in GPS records location, speed, and time data with every journey. Dual-band 2.4/5GHz Wi-Fi connectivity (Wi-Fi dongle required per Australian configuration) enables fast video download and settings management via the Vueroid App.
Vueroid App and PC Viewer: The Vueroid App enables live footage viewing, video download, settings management, and firmware updates from a compatible smartphone. The PC Viewer supports detailed playback with driving speed, G-sensor data, and GPS location history.

Frequently Asked Questions
What is the front camera resolution on the D21-4K?
The front camera records in 4K Ultra HD at 3840 x 2160 and 30fps via the Sony STARVIS 2 IMX678 image sensor, providing cinematic-quality footage with fine detail for licence plates, road signs, and incident documentation.
What is Ultra LP Capture?
Ultra LP Capture is Vueroid's licence plate identification technology that identifies vehicle licence plates both when stationary and while moving, and in very low-light environments. This is particularly valuable for capturing evidence in hit-and-run incidents and night-time collisions where standard cameras may produce unreadable plates.
How many ADAS alert types does the D21-4K have?
The D21-4K AI ADAS system delivers six alert types: Forward Pedestrian Detection (FPD), Rear Pedestrian Detection (RPD), Forward Collision Warning (FCWS), Rear Collision Warning (RCWS), Front Vehicle Start Alarm (FVSA), and Lane Departure Warning (LDWS).
Does the D21-4K require a Wi-Fi dongle?
Per the Australian product configuration, Wi-Fi functionality requires an optional Wi-Fi dongle. The unit features built-in dual-band 2.4/5GHz Wi-Fi hardware; confirm dongle requirements with your supplier before purchase.
What is the difference between the D21-4K and the D20-F2?
The D21-4K records the front in 4K UHD via Sony STARVIS 2 IMX678 with AI ADAS (6 types including pedestrian detection), Ultra LP Capture, Ultra Night Vision, flexible voice recording modes, and GPS built-in. The D20-F2 records both front and rear in Full HD 1080p via Sony STARVIS with standard ADAS (4 types) and requires an optional GPS antenna.
